I don't want everyone to hate me. LOL I was 125 lbs when I got married at age 21. You could count my ribs up until about 25 or so. I was painfully thin. I have a very high metabolism. Everybody that knows me will tell you that I am very high strung. Please don't hate me! 
And yes, my grandmother said he started smoking at 6 yrs old. BUT, I must say he grew up on a farm and didn't have a sedentary lifestyle.
GA, I've been skinny all my life because of a high metabolism as well. I've always been trying to gain weight, and it's not been until recently that I have been filling out because of weight training and a high protein diet. I'm currently 6'3 and 180, which according to the weight calculator on the web, is right on point (179). This is reason for celebration, because I've always been a lanky fool (let's be honest, still am).
The road to 40 inch biceps in long and barren. 
I began filling out around age 25. My pecs finally filled out and my legs and arms began to bulk up. It's about time. I'm 37 now and probably look better physically than I have my entire life. I eat red meat, chicken, fish whatever. I LOVE vegetables and fruits. I just eat whatever and seem to maintain my 155 - 160. Oh yeah, and BEER!
